The newest water ride at the Oktoberfest is the only one with spinning rafts. Due to its mild slopes, it's also suitable for smaller children.

Since the 80s, flume rides made eyes of young Oktoberfest visitors sparkle. For many years, there was no alternative to the classic log flume rides, until in 2011 a new kind of water ride made its way to the Oktoberfest. In contradiction to the log rides, Rio Rapidos has only very mild slopes, which makes it suitable for smaller children, are afraid of the way faster taller water rides.

The more than two minutes long ride consists of two different sections: a faster water-slide-like part following the lift and a slower, rafting-like part.
